You are right, @op. People keep changing strategies because they are trying by all means to avoid losses, which is quite impossible. Trading requires consistency in addition to the skills and knowledge already acquired. No matter how good a strategy may be, there will still be some bad days when losses are unavoidable.
For those who are still trying to find the best strategy to minimize their risks and maximise profits, they can start with a small capital. Then, over time, when they find what works for them, they can scale up.
Changing strategy will never make you a profitable trader, it is just like one who happens to be jack of all trades and master of none. Keeping up with one strategy is the best and when you stick to it, you can make it in trading faster because you get to master the skills more and more. Learning makes perfect and when you’re perfect at it, it becomes stick to you and a knowledge you can never do without. Sticking to one strategy is what most profitable traders are onto and they’ve made it far while using that one strategy. This gives you ample time to become better and become better in your trading. One strategy is enough to be a profitable trader.
One thing many traders do not know is that strategies do fade and we should always have the mindset on developing our strategies so that we don't keep using it even after it had fade up. I have seen different occasions when newbies traders were complaining about why their strategies are not working effectively the way it used to, giving them frequent profits.
Trading is all about learning because the market structure do change often and when we don't work with the current trend, we could make more mistakes than we ought to make. The crypto market is vast and it's not only about making the money but knowing the best time to buy or sell so that we don't incur unnecessary loses just because of lack of information.
